Hi all!
This is my first post here, though I’ve been doing a lot of reading on here. Sorry for the long post!!
My fiancé purchased a used Freightliner DD15 back in February. We’ve been having issues after issue, out of 4 months we’ve been in the shop I think 3. We’ve had major work, thankfully most of it cover by warranty. We’ve had the cylinders replaced, head gasket, one box, filters, you name it. Some of these components replaced more than once. We’ve had Detroit, Freightliner Corp. involved in this ordeal.
After 3 weeks of the truck running fine, we are back in the shop, same issue lights go on and the truck derates to 5mph. We are at a loss here as we’ve spent more time in the shop than running the truck.
Trying to see if anyone could offer some clues as to what could be wrong. We’ve even considered getting rid of the truck.
Below are the codes the shop informed us we are getting now:

Thanks for any guidance you can provide!

What year freightliner?
-
I'm guessing injector 6 is bad. What do they want to do with it?
-
Jarhed1964 and 77fib77 Thank this.
-
Farmtractor9900 and baha Thank this.
-
Have they tested the injectors with a thermal scanner while the engine is running?
Have they visibly inspected all wiring harnesses and connections?
Have you used different shops, or do you keep taking it back to the same one?shanman Thanks this. -
We’ve used a different shop every time. The truck gets fixed, we run and it breaks down, sometimes the truck will run 3 weeks once it has been fixed, a few days and in one instance it broke down within two hours of leaving the shop!. We’ve been to shops on WV, Flagstaff and Tolleson, AZ, New Mexico, Florida. We spent one month at the Tolleson location while they tried to figure out the issue, and then replaced the head gasket.
It really is very frustrating.
Thanks! -
Play musical injectors. See if the computer follows the code or the actual injector.
no ones trading in a 2017 truck because it is running too good…..Jarhed1964, Rubber duck kw and dwells40 Thank this. -
They should have replaced all the injectors the first time around.
Second is never buy a truck without doing your due diligence, OA, dyno/blowby, ECM dump, dealer vin check and so on.shatteredsquare Thanks this. -
Sounds to me like its either a wiring problem, or something mechanical inside the engine. You need a real mechanic to start taking it apart and hunt down the problem.Farmtractor9900 and baha Thank this.
